performance - how can I simply benchmark my linux application -

Imagine that you write applications, options for some current version and you want to compare if it is more effective or No,

you just use time as

  time for your order timeout order   
 And can compare performance time to examine some difference, but it is not very wide  
 Is the same command to check more data? Is it? Such as memory usage, CPU usage, CPU peak, memory peak etc ...   
 
 
 A good implementation  Time  actually tells you much more than the clock in the wall, most Linux systems have one, but Bash is in the habit of obscuring it in favor of the built-in time, so you can call it  / usr / bin / time Calling as :  
  $ / usr / bin / time python -c "numpy as np; np.empty (100000)" 0.12user 0.00system 0: 00.13 Ended 96% CP 0inputs of U (0avgtext + 0avgdata 12860maxresident) + 0outputs (0major + 3777minor) Pagefelt 0swaps   
 This is a simple Python command for CPU usage, memory usage and many other statistics. Manap  Time (1)  See what  time  can do.
